以六氯环三磷腈（HCCP）为单体，采用沉淀聚合法制备了新型含氟交联聚磷腈微纳米球。利用SEM和TEM研究了分子结构对聚磷腈微纳米球形貌的影响。采用傅立叶红外光谱、X射线光电子能谱和热重分析等手段对微纳米球进行了表征。结果表明，5%热降解温度为366 A ℃。发现浸涂有由此制备的微纳米球的硅晶片具有高达137 A度A +/- A 1.5 A度的水接触角。此外，还讨论了HCCP浓度和超声功率对产物形貌的影响。
Novel fluorinated cross-linked polyphosphazene micro-nano spheres have been prepared by precipitation polymerization of hexachlorocyclotriphosphazene (HCCP) monomer. The influence of molecular structure on the morphology of polyphosphazene micro-nano spheres was investigated by SEM and TEM. The micro-nano spheres were also characterized by Fourier transforms infrared, X-ray photoelectron spectroscopy and thermo gravimetric analysis. The results indicate that the 5 % thermal degradation temperature is 366 A degrees C. It was found that a silicon wafer dip-coated with thus prepared micro-nano spheres has a water contact angle as high as 137A degrees A A +/- A 1.5A degrees. Furthermore, the effects of the concentration of HCCP and ultrasonic power on the morphology were also discussed.
